【摘要】 纤维作为SMA混合料的稳定剂,对混合料的性能有重要的影响,沥青混合料中纤维的加入能够提高混合料的高温稳定性、水稳定性、低温抗裂性等性能。本次研究在钢渣SMA-13混合料中掺加玄武岩短切纤维和颗粒状木质素纤维,通过浸水马歇尔试验、车辙试验、冻融劈裂试验、低温弯曲试验等来分析不同纤维对钢渣SMA-13混合料性能的影响。试验结果可供钢渣SMA-13混合料在选用纤维时作重要的参考。更多还原

【Abstract】 Fiber as stabilizers of SMA mixture,have important influence on the performance of the mixture,join the fiber asphalt of mixture can improve the high temperature stability,water stability,low temperature crack resistance performance of the mixture,etc. The study in steel slag SMA-13 mixture respectively mixed with chopped basalt fibers and granular lignin fiber,through the immerseable Marshall test,rutting test and freeze-thaw splitting test,low-temperature bending test and so on to analyze the different fiber on the properties of steel slag SMA-13 mixture. The test results for steel slag SMA-13 mixture when choosing fiber as a important reference.更多还原
